LUBBICATOR AND RESERVOIR FOR INTERNAL-COMBUSTION ENGINES..

To all whom it may concern:

Be it known that we, Emma 15). LARCH and CLARENCE C. BROWN, citizens of the United States, residing at Boswell, in the county of Benton and State of Indi. na, have invented certain new and-useful Improvements in Combined Lubricators and Auxiliary Oil-Reservoirs for Internal-Combustion Engines, of which the following is a specification. d

This invention relates to an improved lubricator and auxiliary oil reservoir for internal combustion engines and has as its primary object to provide a device of this character particularly adapted for use upon. engines or motor vehicles of the Ford type.

The invention has as a further object to provide a device adapted for connection to the breather ipe of the en 'ne and provided with a pluraiity of suitab y arranged openings so that air may enter therethrough into the engine crank case.

And the invention has as a still further object to provide. a devicewhichwill be simple and efficient in construction and wherein a manually operable valve will be employed for feeding the quantity of lubricant desired through the breather pipe of the engine into the engine crankcase.

Other and incidental objects will appear as the description proceeds and in the drawings wherein we have illustrated the preferred embodiment of the invention and wherein similar reference characters designate corresponding parts throughout the several views:

Figure 1 is a fragmentary side elevation showing our improved lubricator and reservoir applied to a conventional engine of the Ford type, this view being partly broken away to illustrate the mounting of the device upon the breather pipe of the engine.

showing the mounting of the screen in the discharge tube-leading from the container.

In order that the construction, mounting and operation of our improved device may be accurately understood, we have, in the drawings, shown the device in connection with a conventional engine 10 of the Ford type. This engine is, as is well known, provided' with a breather pipe 11 through which oil is introduced into the crank case of the engine. The breather pipe 11 is, adjacent its upper extremity, formed with an internal annular shoulder 12 and extending diametrically through the said pipe below the said shoulder is a bolt 13 securing the spring arm 14: which holds the cap of the engine commutator in position. a

Coming now more particularlv to the subject of the present invention, we employ a preferably cylindrical container 15. This container may, of course, be varied inrsize, as found desirable, and closing the lower end of the container 'is a bottom wall 16 having an annular series of discharge openings 17 formed therein. -Screw threaded upon the upper end of the container is a closure cap 18. a L

Extending from the lower end of the container is a discharge pipe 19 slidably .fit ting into the upper extremity of the breather tube 11 of the engine 10 and off-set adjacent its lower extremity to provide an annular shoulder 20 from which projects a reduced extension 21. The shoulder 20 is arranged to engage theshoulder 12 of the pipe 11 for supporting the container upon the said. pipe and formed through the reduced extension 21 are diametrically arranged openings 22 freely receiving the. bolt 13 which thus acts to rigidly connect the device with the breather pipe. Adjacent its upper extremity the discharge pipe 19 is exteriorly screw threaded to receive a nut or collar 23 and interposed betweenthis collar and the 'upper end of the breather pipe is a gasket 24 adjustably engaged by the nut to provide a tight joint between the discharge pipe and the breather pipe of the engine. Furthermore, ,it is to be observed that by adjusting this nut downwardly, the discharge pipe 19 of the container. will be lifted into binding engagement with the bolt 13- to thus overcome any rattling between the parts.

A it will be observed that the Projecting into the container from the bottom wall 16 thereof is a spider the arms of which rise from the said bottom wall and conver e to support the sleeve 26 of the spider axlally of the container. At its lower end this sleeve is preferablyconnected with the said bottom wall. Shdably= fitted through the spider sleeve 26 as well as through the cap 18 of the container 15 is an axially arranged valve stem 27. This valve stem projects freely through the bottom wall'16and at its lower end carries a valve 28 adapted to overlie the discharge openings 17 in the said bottom wall. The valve 28 may be formed of leather or other suitable material and support' the said valve is a metallic washer 29 hel by a cotter-pin or other suitable fastenin device 30 fitted through the lower end .0 the valve stem for connectingthe washer and valve thereto; Surrounding the valve stem within the container 15 is a helical spring 31. One end of this spring bears against a washer 32 carried by-the valve stem to rest a inst the spider 25 while the opposite end 0 the said spring engages a similar washer 33 heldupon the valve stem by a cotter pin or other suitable fastening device 34, Thus spring 31 will normally maintain the valve 28 closed.

As will now be readily understood, the container- 15 may, by simply removing the cap 18, be filled with a lubricant. When it is desired to introduce a portion of the lubricant into the crank caselof the engine this result may be readily accomplished by simply depressing the /alve 27 to unseat the valve 28 when the lubricant will flow through the discharge openings 17 of the container into the discharge pipe 19 and through the breather pipe 11 to release of the va ve stem, the valve 28 will be immediately vclosed by the spring 31. This provides a very simple and convenient arrangement for lubricating the engine while at the same time the container 15 will form an auxiliary reservoir for the engine lubri cant. Removably fitted within the discharge pipe to rest upon the shoulder 20 thereof is a suitable screen 36 adapted to strain the lubricant as it passes into the engine crank case. Iaorder that air may be admitted to the engine crank case, the discharge pipe 19 is, at a point slightly below the bottom wall 16 of the container, rovided with a series of circumferentia 1y spaced openin 37 through which the engine may free y breathe and arranged to overhang the said openings is aguard flange 38. This flange -is preferablyintegral with the discharge a pipe and will tehcl us prevent dirt or other the discharge pipe'to thencebe d foreign matter from finding its I Way into iwn into the engine crank case. Furtheiinore, the

screen 36 will also perform-a function in the engmecrank case. Upon the associated with the same time the device is of such nature that,

it may be readily applied to a conventional engine of the Ford type without the necessity. for any structural change therein.
